Title: 48V 3KW BLDC Hall Sensor Sequence and angles
Post by: BrianWard777 on January 29, 2019, 05:45:10 PM

Hello all,

I'm new to working with these motors and have some trouble getting the motor controller programmed for them. I originally was using two VEC200 controllers, however, they ended up not working out for our project. I have since switched to a Roboteq dual motor controller.

My problem is that I can not seem to find any information about what the hall sensor angles (and offsets if any) are, nor any info on hall sensor sequence/order. Does anyone have any info on this? I've tried contact golden motor but have not gotten any kind of response.

Thanks in advance!

Hi Brian and(https://i.imgur.com/evDSMvT.png)to the forum.

Unfortunately there is very little available regarding the technical specification of those motors. :(

Regarding the Phase sequence, the original configurations on the GM controller are shown below:

U = Yellow
V = Green
W = Blue 

I think the Phase angle is 120° but no idea about Hall Sensor angles or offsets.

The following diagram may help as I believe the 3kW motor is pretty much the same layout as the 5kW motor shown:

So for clockwise rotation, I'm guessing that the Hall Sensor sequence will presumably be Yellow > Green > Blue.

I believe the 3kW motor also has 24 coils and 8 magnet (4 pole pairs).

I hope some of this is useful.

Hi Alan,

I know this post is old, but I plan on developing a ESC for the HPM3000B as a final project for my Graduate Degree and would like to confirm this information:

So you believe the rotor and stator have 4 pole pairs?

24 coils / 3 phases = 8 coils per phase = 4 pole pairs
8 magnets = 4 pole pairs

Thats it, right?
I plan on running some tests on the motor to confirm this. (Comparing speed and wave frequency)

8 magnets = 4 pole pairs

The 3kW and 5kW rotors both have 8 magnets (4 pole pairs) as shown below:

But I don't know if the stators now have 24 coils like this 5kW motor;

(http://arhservices.co.uk/GoldenMotor/hpm5000b%20correct%20magnet%20polarity_zpslfcaxj42.JPG)

as this 2012 5kW stator only had 12 coils (4 coils per Phase):

You can find more useful information (https://www.miromax.lt/userfiles/6/images/HPM%20motors%20technical%20data.PNG) on the Miromax website (https://www.miromax.lt/en/m-6-eko_transportas).

It will be interesting to see the results of your tests.
